Mixed CP and SVC Conferencing
In a Mixed CP and SVC conference, SVC endpoints transmit multiple resolutions and
temporal layers to the Collaboration Server like the SVC-based conferences, while AVC
endpoints send only one H.264 AVC video stream to the Collaboration Server. The
Collaboration Server relays SVC-decoded video bit streams to the SVC-enabled endpoints in
the conference according to their display capabilities. This enables the video conference
layouts to be automatically assembled by the endpoint. AVC endpoints connected to the
conference send a single H.264 AVC video bit stream to the Collaboration Server, which is
then transcoded to SVC video streams. SVC-enabled endpoints receive the AVC converted
video bit streams through the Collaboration Server from the AVC endpoints as a single SVC
video bit stream. Alternatively, AVC endpoints receive a single video bit stream with the
defined video conference layout from the Collaboration Server. In this mixed mode
conferencing, both SVC and AVC endpoints in the conference receive the same CP layout.
